iPhone 4 ceramic, glass materials update

Published on June 7th, 2010 | By: pwray@ceramics.org

New iPhone 4 with glass back and one of three "seams" that are part of antenna system.

Steve Jobs has been revealing feature after feature of Apples new iPhone for the past hour and it looks more loaded with glass and ceramic materials than I first anticipated.

Here’s a partial rundown:

  • Front: Clear glass
  • Back: Black glass
  • Side seams: glass or ceramic that function as part of antennae system
  • Display: 326 ppi LED “Retina Display”
  • New Sensors: gyroscope, compass, proximity and ambient light
  • Flash: LED for still and video recording
  • Lithium-ion battery
"We developed a glass that's 30 times harder than plastic," says Steve Jobs at the WWDC'10.

Apple seems to be jazzed about their new glass (and we hope to provide a link to a video about it ASAP) and here is what the website says:

“Engineered Glass
All the breakthrough technology in iPhone 4 is situated between two glossy panels of aluminosilicate glass — the same type of glass used in the windshields of helicopters and high-speed trains. Chemically strengthened to be 20 times stiffer and 30 times harder than plastic, the glass is ultradurable and more scratch resistant than ever. It’s also recyclable.”

The manufacturing of the case and glass is discussed at the 4:50 point in the official Apple video:

  1. Peter Wray says:

    At our just-completed Ceramic Leadership Conference, I (unsuccessfully) tried to get a few people from Corning to go on the record about the iPhone glass. No luck, but lot’s of comments along the line of, “Boy, Apple is a great company and it’s very, very nice to see the advanced sales numbers.”

    There are a few exceptions, but Apple’s culture is to discourage individual suppliers from sharing the spotlight.

  2. According to the teardown at iFixit.com (http://www.ifixit.com/Teardown/iPhone-4-Teardown/3130/3), Corning’s Gorilla Glass is used on the front and back of the iPhone 4 (http://www.corning.com/gorillaglass/index.aspx).

  3. I’ll be looking forward to a more detailed analysis of the materials. The claim that “we developed a new kind of stainless steel” sounds a bit over-the-top, but the video of the three-point bending test of the glass front and back was definitely impressive.
